WebJan 2, 2024 · Knowing that turbulence is caused by changes in wind velocity (the speed and direction), it is then possible to predict scenarios where turbulence may occur. The boundary layer. The most simple form of turbulence, both close to the ground and up in the air. Winds rarely blow consistently so changes in this velocity will result in turbulence. WebNov 18, 2024 · The alternative and/or contributing cause of change in wind speed is due to change in land surface roughness. It is very unlikely that change in roughness alone has caused the change in wind speeds.

Generally speaking wind speed increases with height above the surface as the frictional force of surface diminishes with height. The friction imposed on air mechanically slows the wind and diverts its direction. The friction layer is the layer of air that is influenced by friction caused by the surface. human company rotterdam
